To all 'whom 'it *ma/y concern.'

Be it known that I, WILLIAM M. TEMPLE- from,4 citizen of the United States, residing at Averyville, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Lubricators; and I do hereby declare that the following is a full; clear, and exact description of tlle invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lubricators of the sight-feed type.

An object, as in other devices of which I am aware, is to provide a structure for nebulizing or atomizing a lubricant and introduce it in `that state into a cylinder or other art to be lubricated whereby all of the sur aces lof Jsaid cylinder or part will be thoroughly and evenly coated therewith. e

Another object is to provide a new structure, in a lubricator by which the `lubricant will be lvery nely divided so that it will be evenly and thoroughly distributed upon the wearin surfaces. y

In a dition to the above objects the invention relates to certain details as will be pointed out herein but before entering upon the description of my device some of its advantages will be outlined.

Oil is quite heavy and when introduced into a cylinder it naturally falls upon and lies inthe lowest part of said cylinder and only'lubricates that portion. In mylubricator the oil is introduced into the cylinder' in a nebulous form b being thrownwith 'great force u on and tliyrough a member, preferably a oraminated one, by ywhich it 1s' very finely'"thandedV and nebulzedjso aste; 'ass 4in that form to and u on allf'of the sur acesof the cylinder. In a di'tipn to' this advantage my improved lubricator may'be used 1' in a zero temperature and perform its duties as perfectly as in a warm rooifn from the fact that live steam, which constantly circulates throughit, keeps lits Anietalaiid the oilhot. Sincei live steam -`is -censtantly lcirculatin through my lubrieatorthe `o il can be'v kept a A an even temperature so that when the device is adjusted to feed a certain quantityofoil the rate of feed will he constant under all variatiens'fof exfternaltem raltarre. In the appended drawlng:-Fi e 1 is a vertical section of my improved sight'ieed,v lubieator. Fig. 2 isa planl of the same with,

parts broken away. Fig. 3 is a vertical section of the lubricator on line X X, Fi 2. Fig. 4 is a vertical section of a portion org the lubricator on line Y Y, Fig- 2, as viewed in the direction of the arrow.

The body of the lubricator consists of a cylinder or shell B the two being cast as a single member as indicated in Fig. 2; the wall of the inner cylinder B and the wall of the cylinder A being connected at 'oneside for convenience in more easily connecting a steam pi e into said inner cylinder B as will be descri ed later, and the top and bottom walls or ends C C serve to cover both cylinders and to separate one from the other of construction so as to form two separate receptacles. At the to of the'cylinde'r B the upper end C is provi ed with an opening D preferably of the full inner diameter of said cylinder; said openin being provided with screw threads to receive a threaded plug E. The 'space within the cylinder A rovided for receiving and holding oil whic is supplied thereto through a hole F closed by a plug F; Figs. 2 and 3, in the top wall.

Placed 'within' the cylinder B is a diaphragm G inserted through the opening D said dia hragm being foraminated or in the form o ai wire stralner of very fine mesh which lies in A lace for vinstance u on a shoulder G forme inthe wall of saidp cylinder B, or supported and held in place in yany other desire way,r'sa,id diaphragm havinga osltion aishcrtldistancejahove the bottom o the c linder or about as "shown Preferably in tlie'bottom ofthe cylinder A is 'a substa bore H extendtially horizontally disposed ing through an integrallcast lportion J said boefcommunicatingatl one en with the cylinderB and extending through the outer wall'| of the cylinder? A, as Yshown in Fig. 1 there being a conduit K connected into the said bore -through which con it the lubricant-is introduced into the e gine cylinder (not shown). Also in the bottom of the device is a second boreL extend' through an enlargement for heavier part sani bore o Aening' through that' portion of the wall of tv e devlce where the cylndersA and B converge and "oin. Connected into the outer end bf said ore Lis a valve N,which carr1es a, 'lass column() preferably filled, as 1n compractiee, wit a uid suchl as water or r?'1gl;yfcern. The upper end of said column 1s cylinder or shell A within which is a smaller.

preferably carried by and communicates with the o en end of a pipe P whose other end is threa ed into the wall of the device and terminates Within the cylinder B. Connected into one end of the bore L at the top of the enlargement M within the cylinder A is a stand pipe Q. the upper end of which terminates int e top of said c linder A.

R is pipe or supplying live steam to the engine and with this is connected a pipe S provided with a valve T said pipe leading into the top of the cylinder B through the plug E, the latter being properly bored and threaded to receive said pipe and to provide a steam tight joint. Connected with said pipe S is a pipe U which extends through the top of the cylinder A and extends preferably down to the bottom'of the latter and serves to supply water of condensation to said cylinder to replace th'e oil as it is used.

The operation of the device is as follows The cylinder A, is lled with oil to the top of the stand-pipe Q by removing the plug F. The glass column O is also lled with water or glycerin, the valve N being closed, of course, to prevent the fluid from passing into the bore L and rising in the said stand pipe Q. Steam is now admitted into the pipe S by opening the valve T. This introduces live steam into the cylinder. The oil which runs down through the stand pipe Q reaches the valve N and the adjustment of that member provides for the desired rate of flow of the oil into and up through the glass column O. After passing said valve the oil rises through the fluid in said column and iows along the pipe P into the cylinder B and meets the steam jet issuing from the nozzle constituted by the discharge end of the pipe S in said cylinder. As the oil leaves the inner end of said pipe P drop by drop it is caught by the steam and driven with great forcev upon and through the diaphragm G causing it to be very finel broken up or nebulized and in that condition is carrie-d along with the steam through the bore H and pipe K and deposited in the cylinder upon all of its walls. As the oil is removed little Vby little from the cylinder A it is replaeedby water of condensation introduced into the cylinder A through the pipe U, the latter being preferably extends down to the bottom of the cyllinder, as already stated, so as to deposit t e water at once at the lowest point in order to raise the oil instantly to restore it to its original level. Since is a tight y there is a certain constant pressure upon the oil due to the steam pressure throu h the pipe U which pipe also must natural y contain water of condensation; the temperature of the oil being lower than that of. the steam and causing such condensation. Now, as a portion of oi passes out of the cylinders through the stand-pipe Q, the pressure tends to lower slightly but is at once balanced by the entrance of an amount of water equal to the bulk of the oil released.

In order teclear the cylinder A and let out the water which has finally taken the lace of the oil I provide a cock V in the ottom of the cylinder. This when opened permits the discharge of the water and all foreign matter such as grit which may have entered with the oil and just here another of the advantages of my lubricator may be mentioned. Since the oil is always kept hot and is consequently thin, any grit and other foreign matter carried by the oil will readily sink to the bottom of the cylinder. The top ortion of the oil beingnaturally free from oreign `matter therefore enters the engine cylinder perfectly clear of all injurious mat# ter likely to abrade the metal surfaces-and when cleaning the cylinder A through the cock V the foreign matter left behind will be discharged.

The usual gage glass W is indicated in Fig. 2 this being used in order that the height of the oil may be determined at all times.

The construction of the lubricator may be changed in one manner or another so long as the objects sought are accomplished since I lo not wish to be confined particularly to what is shown.

Having thus described the invention, I claim Y 1. In a lubricator, a single hollow castinv` having a substantially vertically disposed dividing wall separating its interior into two compartments, one of them for oil, the other for steam, a pipe erected in the oil receptacle and terminating in the upper part thereof its passage communicating with the steam receptacle, a steam pipe having a branch terminating in receptacle and a branch terminating in the said steam receptacle, and a discharge pipe connected with the latter.
